Adult: Once the adult house fly hatches from the pupal stage, it has an approximate life span of 15 to 30 days. Females are able to start producing eggs after two days of life and will continue to lay eggs for about a month. Female house flys are usually larger than the males.
The average natural life span of fruit fly adults in optimal temperatures is 40 to 50 days. Female fruit flies are capable of mating and laying several batches of eggs in that time, allowing the fruit fly population in a home to multiply quickly. The life span of the fruit fly is heavily influenced by temperature.
